Once again, for all the Open Theists (Especially the MAD Open Theists).
(Psalm 139:2) .....You know my thoughts before I think them.
Another view the actual Acts 9 Position does not hold to - Open Theism.
But all that passage is asserting is that God is able to read a man's heart.
The same is said of His Word...
Hebrews 4:11 Let us labour therefore to enter into that rest, lest any man fall after the same example of unbelief. 4:12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. 4:13 Neither is there any creature that is not manifest in his sight: but all things are naked and opened unto the eyes of him with whom we have to do.
And the same was the case with the Son...
Luke 6:6 And it came to pass also on another sabbath, that he entered into the synagogue and taught: and there was a man whose right hand was withered. 6:7 And the scribes and Pharisees watched him, whether he would heal on the sabbath day; that they might find an accusation against him. 6:8 But he knew their thoughts, and said to the man which had the withered hand, Rise up, and stand forth in the midst. And he arose and stood forth.
And the same was the case with the Spirit...
Acts 5:1 But a certain man named Ananias, with Sapphira his wife, sold a possession, 5:2 And kept back part of the price, his wife also being privy to it, and brought a certain part, and laid it at the apostles' feet. 5:3 But Peter said, Ananias, why hath Satan filled thine heart to lie to the Holy Ghost, and to keep back part of the price of the land? 5:4 Whiles it remained, was it not thine own? and after it was sold, was it not in thine own power? why hast thou conceived this thing in thine heart? thou hast not lied unto men, but unto God.
